It tells the story of Inara, a cheerful, smart, and unique girl who lives in a world of her own. Even her best friend, Nadiva, sometimes thinks Inara is strange because she often spends her time simply gazing at the sky. In fact, the Three Crystals Gang really hates Inara, whom they consider odd. The story goes that while attending summer camp, they meet Arjuna, a mysterious, handsome guy; Nolan, Arjuna’s friend who’s just as handsome but a playboy; and Fanya, Arjuna’s fiancée—a beautiful, smart, sassy girl who’s extremely overprotective of him. One day, while Inara was standing on the beach just to gaze at the sunset, she accidentally ran into Arjuna, who thought she was going to commit suicide. That’s how the two of them became friends. Arjuna felt that Inara was different. However, Inara didn’t know that Arjuna actually suffered from cardiac arrhythmia.
